Description
Bekanntlich werden hochwertige Stahlsorten, insbesondere Schnellarbeitsstahl, wegen ihrer Kostspieligkeit nur in derart kleinen Stücken in Benutzung genommen, daß ihre Länge kaum größer ist als die Stärke der wirksamen Arbeitskante.It is well known that high-quality types of steel, especially high-speed steel, are due to their costliness has only been used in such small pieces that their Length is hardly greater than the strength of the effective working edge.
Diese Stahlplättchen werden auf Trägern befestigt, welche die übliche Form der altgewohnten Werkzeugstähle haben, so daß sie ohne weiteres in die Supporte, Stahlhalter, Futter o. dgl. eingespannt werden können. Die Plättchen müssen wegen der Höhe der Beanspruchung, der sie beim Arbeiten ausgesetzt sind, sehr fest mit dem Träger verbunden sein.These steel plates are attached to carriers, which have the usual shape of the old ones Have tool steels so that they can be easily clamped in the supports, steel holders, chucks o. The platelets must because of the level of stress they are exposed to when working must be very firmly attached to the carrier.
Bis jetzt erfolgt die Befestigung der Plättchen am Träger durch Schweißen oder Löten. Beide Befestigungsarten verlangen eine ziemlich starke Erhitzung der Träger und Plättchen. Dies bildet einen Nachteil, weil durch die hohe Erhitzung die Gefahr des Verbrennens des Plättchens entsteht. Außerdem sind die bekannten Befestigungsarten umständlich, kostspielig und zeitraubend.Up until now, the platelets have been attached to the carrier by welding or soldering. Both types of fastening require a fairly strong heating of the carriers and plates. This constitutes a disadvantage because the high temperature creates the risk of burning the plate. aside from that the known types of fastening are cumbersome, expensive and time-consuming.
Allen diesen Nachteilen hilft die Erfindung dadurch ab, daß sie das Plättchen sowohl wie den Träger nur örtlich und auch nur so weit erhitzt, als dies zur Herbeiführung einer dauernden Haftverbindung notwendig ist.All of these drawbacks remedied by the invention in that they both the plate as heated the carrier only locally and only to the extent necessary to induce a permanent adhesive bond is necessary.
Die Erfindung besteht in der Anwendung der Umwandlung von mechanischer Arbeit in Wärme, und zwar in der Weise, daß Plättchen und Träger, die auch vorgewärmt sein können, aneinandergedrückt und dann gegeneinandergerieben werden. Die reibende Bewegung kann eine drehende oder eine schwingende sein; z. B. ist es möglich, das Plättchen in eine Vorrichtung einzuspannen, es sohneil sich drehen zu lassen und den Träger dagegenzudrücken. Nach dem Maße des ausgeübten Druckes und der durch die Drehung des ■ Plättchens erzeugten Reibung steigt die Temperatur an der Berührungsstelle alsbald an. Bei zweckentsprechender Einstellung von Drehzahl und Druck erhitzen sich Plättchen und Träger an der Berührungsstelle so weit, daß ein Fressen und demnächstiges Haften durch Verschweißung oder eine Art der Verschweißung zwischen Plättchen und Träger stattfindet. Man kann auch das Plättchen in eine mit entsprechend hoher Schwingungszahl hin und her schwingende Vorrichtung einspannen, den Träger andrükken und auf demselben Wege wie vorbeschrieben die Haftung herbeiführen. Dies hat den Vorteil einer gleichmäßigeren Erwärmung über die ganze Ausdehnung der Haftfläche. The invention consists in the application of the conversion of mechanical work into Heat, in such a way that the platelets and carriers are also preheated can be pressed against each other and then rubbed against each other. The rubbing movement can be rotating or oscillating; z. B. it is possible to use the platelet clamp in a device, let it rotate and the carrier to push against it. According to the amount of pressure exerted and that caused by the rotation ■ the friction generated by the plate, the temperature at the point of contact rises immediately. With appropriate Adjusting the speed and pressure, the platelets and the carrier heat up at the point of contact so far that seizure and soon sticking by welding or some kind of welding between platelets and carrier takes place. You can also turn the platelet into a correspondingly higher one Frequency of oscillation Clamp the device that vibrates back and forth, press on the carrier and bring about liability in the same way as described above. this has the advantage of more even heating over the entire extension of the adhesive surface.
Es kann ferner auch so verfahren werden, daß ein körniges oder pulverförmiges Haftmittel, ζ. B. Stahl oder Lot, in fein verteiltem Zustande zwischen die Haftflächen gebracht wird, die entweder wie im Falle des Stahlpulvers die Erhitzung beschleunigen oderIt can also be proceeded in such a way that a granular or powdery adhesive, ζ. B. steel or solder, brought in a finely divided state between the adhesive surfaces which either accelerate the heating as in the case of steel powder or
wie im Falle des Lotpulvers gleichzeitig den Temperaturgrad herabsetzen, der zur Bildung der Haftverbindung nötig ist.As in the case of the solder powder, reduce the temperature level at the same time, which leads to formation the adhesive bond is necessary.
Es wird meistens zweckmäßig sein, ist aber nicht notwendig, ausschließlich das Plättchen einzuspannen und zu bewegen und den Träger im Ruhezustand dagegenzudrücken; es kann sich auch empfehlen, den Träger einzuspannen und sich Plättchen und Träger gegeneinanderbewegen zu lassen.Most of the time it will be useful, but not necessary, just the plate to clamp and move and to press the carrier against it at rest; it It may also be advisable to clamp the carrier and move the platelet and carrier towards one another allow.
Zur beschleunigten Herbeiführung des Haftens und zur Ersparnis an Kraft ist es namentlich bei der Ausübung des Verfahrens mit drehender Bewegung zweckmäßig, eine Aussparung vorzusehen. Diese kann entweder am Plättchen oder am Träger vorgenommen werden; sie kann in einer durchgehenden Bohrung oder in einer Ausnehmung begrenzter Tiefe bestehen.It is for the accelerated induction of adhesion and for the saving of strength in particular when performing the procedure with a rotating movement, a Provide recess. This can be done either on the plate or on the carrier will; it can be limited in a through hole or in a recess Depth exist.
Man hat Reibungswärme zum Schweißen bereits bei der Herstellung von Rohren angewendet, wobei aber gegen die noch als Walzgut in der Bildung begriffenen Rohre mit noch offenen Rändern besondere Reibkörper zur Wirkung gebracht wurden, um diese Ränder auf Schweißhitze zu bringen.Frictional heat for welding has already been used in the manufacture of pipes, however, there are special friction bodies against the pipes with still open edges, which are still in the process of being formed as rolled stock were brought into action to bring these edges to the heat of welding.

α bedeutet jeweils das Plättchen, b den Träger, c die Aussparung. Wie in Abb. 3 und 4 beispielsweise dargestellt, können die Haftflächen auch profiliert ausgebildet sein. DiePlättchen können an beliebige Flächen des Trägers angeschweißt werden, können in Vertiefungen eingelassen sein (Abb. 5 und 6) und verschiedene Umrisse haben (Abb. 6). α means the plate, b the carrier, c the recess. As shown in Fig. 3 and 4, for example, the adhesive surfaces can also be profiled. The plates can be welded to any surface of the carrier, can be embedded in recesses (Fig. 5 and 6) and have different outlines (Fig. 6).
